2 Claims.

This invention relates to visible coin slide structures.

One object| of the invention is to provide a coin slide structureadapted to be attached to a cabinet of a coin-controlled orcoin-actuated mechanism and which has a slide element which isreciprocable in the conventional manner for carrying authorized orproper tokens or coins inwardly but which, on the return or outwardstroke and prior to the deposition `of the coins in a receptacle, movesthe inserted coins out- Wardly along a track or guideway where not onlythe last inserted coin but preferably a few of the coins or tokenspreviously inserted are visible to all concerned for the purpose ofdiscouraging the use of spurious tokens or coins or slugs in operatingthe coin-controlled or coin-actuated mechanism such as a merchandisevending machine, for example.

Another object of the invention is to provide a coin slide structurewhich, during the reciprocating cycle of the slidable member rst carriesan inserted coin inwardly and upon the retraction of said member movesthe coin positively outwardly into an inspection or exhibiting sectionof the structure which lis preferably located at the outside-of thecabinet of the coin-controlled mechanism and simultaneously advances thelast few previously inserted coins step by step through said section andthence again into improvements in the cabinet for discharge into a coinreceivingr receptacle or receptacles.

a coin slide structure which can be installed readily in a straight andrelatively narrow slot formed in a cabinet wall without weakening thelatter materially and in conjunction with which slide structure or, as apart thereof, coin and token separato-r means can be employed as, forexample, where the coin-controlled machine is intended for operationwith coins of a predetermined denomination and also with slugs of apredetermined diameter different from that of the coins.

Another object of the invention is to provide a reciprocable coin slidestructure having a member movable inwardly after insertion of a propertoken or coin and thence outwardly to operate or control the operationof the coin-controlled apparatus, such outward movement effecting thedisposition of the releasing token or coin in a position for inspectionas to its genuineness.

Other objects. of the invention relate to various features ofconstruction and arrangement of 'parts which will be apparent from aconsideration of the following specification and accom' panyingdrawings, wherein:

Fig. 1 is a top plan view of a coin slide structure embodying thepresent improvements and showing the same mounted on a wall of a cabinetshown fragmentarily;

Fig. 2 is a sectional view taken on line 2 2 of Fig. 1; y

Fig, l3 is a broken top plan view oi the coin slide structure showingthe slide member moved to innermost position;

Fig. 4 is a broken topfplan viewof a slide structure with the slidemember in an intermediate position;

Fig. 5 is a broken top plan view corresponding to Fig. l butillustrating the preferred shape of the coin exhibiting section of thestructure;l and Fig. 6 is a broken side elevation of the rear portion ofthe slide member and means whereby the operation of a coin-controlleddevice may be energized upon the return or `Voutward stroke of the slidemember. i

In the drawings which disclose embodiments of the invention for thepurpose of illustration, the coin slide structure indicated generally bythev numeral IIJ comprises a base plate member II and a top plate memberI2 which may be formed integrally, if desired, or attached together byscrews or rivets as illustrated. The slide structure is provided with amounting plate I 3 by means of which the structure can be mounted on awall I4 of a cabinet containing the coincontrolled or coin-actuatedmechanism which is t `loe energized by the operationof the coin slidemember as hereinafter described.

As shown in the drawings, the base plate II is provided with a guidechannel l in which a coin slide member I6 is reciprocable in theconventional manner. The slide member I6 is provided with a token orcoin receiving recess I'I in which a token or coin may be inserted whenthe slide member is in the outermost position as shown in Fig. l.`Extending longitudinally from said aperture I'I is a slot I8 which, asshown in Fig. l, is disposed slightly off the longitudinal center of theslide member. Pivotally supported by a pair of ears IS located inwardlyof the mounting plate I3 is a dog 20 provided with an actuating spring2l which retains the dog in sliding contact with the top surface of theslide member I6 adjacent the slot I8 as shown in Figs. l and 2. Shouldthe slide I6 be moved inwardlyl without a coin in the recess Il, the dogwill, of course, drop into the recess and prevent cornplete inwardmovement of the slide. The slide I6 is provided with teeth 22 along oneedge thereof which coact with a dog 23 to prevent inward or outwardmovement of the slide after the same has been moved in one direction orthe ot'her be yond certain limits. Thus, if the slide is moved inwardlyslightly beyond the position shown in Fig. 4, the dog 23 will engage therear-most of a group of teeth and prevent withdrawal of the slide untilthe slide has been moved inwardly a distance wherein the teeth haveclicked past the dog, such as t0 the position shown in Fig. 3. In thisposition, the dog is disposed in a slot or recess la formed in the edgeof the slide member and hence the slide may now be moved outwardlyclicking past-the teeth but until the teeth have moved out of engagementwith the dog or until a second slot Ib is in registration with the dog,the slide member may not be again pushed inwardly. This arrangement, asis well known, requires the operation of the slide throughout itscomplete inward stroke or such portion thereof as is required indelivering the coin to a position of deposit from the slide member aswell as the full outward stroke thereof for effecting the control of thecoin-controlled mechanism as will be hereinafter described.

The plate ll may be provided with a passage 24 therein through whichtokens or coins of a size smaller than is authorized for use in themachine will drop when the slide I5 is moved inwardly. Carried by thecover plate l2 in a recess formed therein is a magnet 25 which isadapted to sustain magnetic slugs in the plane of the slide member andprevent the depositing of the same in a coin receiving passage 26 whichis formed in the plate ll. Stop means such as a pin 21 may be carried bythe magnet whereby when such a magnetic slug is inserted and is of suchsize that the dog 2D does not arrest the inward movement of the slide,such inward movement will be arrested by the contact of such slug withthe pin 2l, it being noted that the pin is disposed within the slot IB.If a coin of a proper denomination is inserted in the slide and movedinwardly, it will retain the dog 2D in the elevated position shown inFig. 2 and hence can be moved inwardly to a position beneath the magnet25 and will be deposited from the recess Il into the coin receivingpassage 26 as shown in Fig. 3. The passage 26 is provided with a rearextension extending throughout the base plate Il beneath the slide I5and also a communicating angular portion 26a which communicates with acoin exhibiting section 26h formed in a laterally extending portion 28of the casing structure. This section 28 may be of the form shown inFigs. l, 3 and 4 but it preferably is curved or arcuate as shown in Fig.5 since, as will be apparent, less force is required to move coinsthrough the arcuate section and a greater number of coins may beretained therein. Means are provided for shifting proper coins or tokensdeposited in the position shown in Fig. 3 along the channel section 26ainto section 2Gb wherein the coins or tokens are visible through theapertured cover plate 28a. of said casing portion, the aperture in theplate being preferably glazed as indicated by numeral 29.

In the embodiment of the invention illustrated, the means referred tocomprises an arm or pusher member 30 which is pivoted at 3| to the slideI6, the member 30 being arranged to operate within the passage sections2li-26a. When the slide I6 is in the innermost position as shown in Fig.3, the forward end of the arm 3i) will be disposed rearwardly of a coin32 deposited in the passage section 26. Upon outward movement of theslide I6, the pivoted member 30 will be directed by the passage 26 intocontact with the coin and move the same through the passage section 26ato a position where the coin is visible through the sight opening orwindow 29. Upon the deposition of the next and succeeding coins ortokens, they will likewise be advanced to the inward position in theexhibiting section 28 of the coin slide structure and the tokens orcoins previously moved into such section will be advanced step by stepthroughout the range of the sight opening and thence inwardly of thecabinet where they may be deposited in a suitable receptacle (not shown)as through a coin receiv ing opening 33 provided in the base plate ll asshown in Figs. 1 and 5.

Where the structure is intended for use with tokens of a smallerdiameter, the base plate Il may be provided with a token receivingopening 34 as shown in Fig. 1 through which such smaller tokens will bedeposited while the larger coins will pass thereover and be depositedthrough the recess 33. Thus, the authorized tokens will be separatedfrom the coins used in operating the coin-controlled mechanism. Wheresuch tokens of smaller diameter are to be used, an inclined slot I'la isprovided in the slide I6 in communication with the coin receivingopening I'l' whereby the dog 2U will be prevented from obstructing thefull inward stroke of the slide during usc of such smaller tokens.

For the purpose of preventing the operation of the coin-controlledmechanism without effecting the disclosure of the coin or token used inso operating it, I prefer to utilize energizing or actuating means forthe coin-controlled mechanism which is operable by the slide only uponthe completion of the outward stroke of the slide which, as abovedescribed, effects the transfer of the inserted token or coin into theexhibiting portion of the structure.

In Fig. 6 of the drawings, the slide IS is shown as provided with alatch member 35 at the rear end thereof which is adapted to engage ahook member 36 pivotally mounted at 3'! to a slidable member 38 providedwith a spring 39 which tends to retain the slidable member in theposition shown in full lines in said gure. When the slide I5 is movedfully inwardly, the latch member will engage the member 36 and upon themovement of the slide to the outermost position, the member 36 willengage a cam or pin 4D and swing it clockwise as viewed in Fig. 6 out ofengagement with the latch 35. During this swinging movement under theaction of the cam 40, a contact 4l carried by the hook member 36 willengage a Contact 42 carried by a spring arm 43 which is mounted at 44 onthe member 38. Upon the momentary closure of the contacts 4l and 42, acircuit through conductors 45 and 46 will be closed which may energizeany suitable control mechanism such as a solenoid actuated switch 4l, orthe like. By this arrangement, it will be seen that the patron mustretract the slide i6 fully to eiect operation of the coin controlledmachine and since such complete outward movement of the slide effectsthe transfer of the used token or coin into position of visibility inthe coin exhibiting section of the device, he can not conceal the factthat he has used a spurious coin or unauthorized token or slug if suchis the fact.

By the construction shown and described, the tokens or coins used inoperating a machine on which the improved slide structure is employedare moved positively by the slide member to a position where theauthenticity of the coin can be determined by mere inspection such as bythe proprietor of the machine or others interested. The arrangement thusdiscourages the use of unauthorized tokens or slugs or spurious coins aswill be apparent. It will be noted that upon moving an inserted coininwardly to the position of deposit shown at 32 in Fig. 3, it merelydrops from the coin aperture I1 into the coin transfer passage which isdisposed vin a plane immediately beneath the plane of the slide. Thisarrangement, therefore, enables the coin to be deposited and transferredto the exhibiting section by means of a structure relatively thin fromtop to bottom. Hence, in mounting the structure, a relatively thin slotonly need be provided in the wall of the machine for accommodating thestructure. This compactly arranged coin slide structure thus obviatesthe formation of a relatively large opening in the wall of the machinein conjunction with which it is used, hence the wall is not materiallyweakened and the required slot in such wall can be formed expeditiously.

While I have shown and described an embodiment of my improvements forthe purpose of illustration, I do not wish to be restricted specicallythereto since various changes may be made therein without departing fromthe spirit thereof.

What I claim as new and desire to cover by Letters Patent is:

l. A coin slide structure comprising a casing adapted to be attached toa wall of a cabinet with portions disposed at each side of said wall, acoin receiving passage in said casing extending from the outer to theinner portion thereof, a second coin passage having intake and outletends located inwardly of the wall and an intermediate portion providedwth a coin `exhibiting opening located exteriorly of said wall,reciprocable means in said first passage for transferring inserted coinsinwardly of the same into the intake end of said second passage, andmeans pivotally secured to and operable by said means for moving atransferred coin into a position of visibility into said intermediatesection on the return stroke of said reciprocable means andprogressively along said sight opening in said passage to the outlet endthereof during succeeding return strokes of said means.
